The following description was taken from a blog
onwww.cpnhelp.org the only CPN forum I could find. It is important to
note the extreme similarities in symptoms, reaction to antibiotics and even the close association
withBabesiosa. Many who are familiar with both diseases have
said,“It's not a far stretch to insert CPNeverywhere lyme/borrelia is inserted.”

"Chlamydia Pneumoniae (Cpn) is a tiny bacterium which is most
often noted for causing a form of pneumonia. Up until the 1970's it was not even isolated and was mistaken for a
virus (its discovery is an interesting story and can be found here:http://www.washington.edu/research/pathbreakers/1989a.html ).

"It was not until 1989 that J.
Thomas Grayston and his associates named it as a separate species of the Chlamydiae. Cpn is very difficult to
culture and so, without modern lab techniques, also to study. It is an intracellular bacterium, which means that it
invades the body cells, and it is an obligate parasite, which means that it cannot supply it's own energy source
and so takes over the energy machinery of the body cells it invades, depleting them and leaving the host cell less
functional.

"Cpn has been implicated in a wide variety of diseases and is
seen by some researchers as a causal factor in particular disease such as Multiple sclerosis, Chronic fatigue,
Asthma, Rheumatoid arthritis, fibromyalgia, chronic refractory sinusitis, cardiac disease, interstitial cystitis,
prostatitis, Alzheimer's disease, Crohn's disease, Irritable Bowel Syndrome and
others."

If you suspect you may have CPN or CPN complications, ask your
doctor to test for PCR testing especially that which is referred to as nested-PCR testing, is considered to have the
highest sensitivity and to be most objective source of serology testing for Cpn.
